My invention relates particularly to skates adapted for roller skatingof all kinds.

The object of my invention is to provide'roller skates, by means ofwhich a far more effective mechanism for supporting the foot or body ofL the skater from the rollers is available. Another mechanism. Anunderslung suspension isprefa erably provided for this purpose. Anotherpurpose is to provide a construction in which the parts tend to becomeself-aligning. Another object is to provide achassis construction forthe skate which can be partly built and completed by the wearer to suitthe most desirable conditions for the individual skater. For instance,

the elastic suspension may be applied or re-;

newecl by the wearer to provide the desired degree of tension orresistance to movement desired by the wearer of the skates and theplates used" for attachment of the skate platform to the rollermechanism may be placed at will, and so as to vary, as desired, theangles to the vertical of the axes on which the two pairs of rollers,with their struts, axles and axle housings, rotate in the turningmovement of the skate while skating. Further objects of my inventionwill be seen from the detailed description hereinafter.

While my invention is capable of embodiment in many dillerent forms, forthe purpose of illus-,

tration I have shown only certain forms thereof hereinafter, which inthe accompanying drawings, in"

In "the drawings,referring first to the form of my invention shown in Figs. 1 to 6, Ihave shown a shoe l of any desired character, having attached thereto aplate 2 of wood, inany desired way, as,

for instance, by screws (not shown). The plate 2,

two front rollers 5 and two rear rollers 6. To the bottom of the plate 2there may be attached a strut in the form of a block 1, of wood or othermaterial, by means of four-screws B. Said block 7 may, also, have on theopposite sides thereof curved recesses 9 and ID to provide ample room inthe turning directions ofthe rollers 5 and 6. Furthermore, the block 1may have front and rear extensions Ii and I2 thereon, through which arod 1 3 extends longitudinally and having screw threaded ends l4 thereoncarrying tapered nuts i5,|6,l1 and I8.

The rod 13 is'underslung beneath axle housings l9 and 20 having thereinaxles 2| and 22, to provideaxial support for the rollers 5 and 6. Asshown in Fig, 4, the axle housings l9 and 20 are then secured abovetherod l3 by wrappings of a cord '23 of rubber or rubber substitute aboutin diameter under tension, or some stretcharound the axle 2| and thescrew-threaded end: of the rod l3. For this purpose there is first ap,-.

plied a spaced spiral wrapping 24 extending 'be-'- tween the nuts I5 andI6 and thenasimilar "or-2 second wrapping 25 above one half of the firstwrapping between the housing ['9 and the'nut'" l6, towards the middle ofthe skate. Then athird series of about three diagonal wrappings 26 aremade around. the. axle housing is and the rod end-l4, and'tjhena' fourthseriesof about three similar diagonalwrappings'z'l at right angles'tothejtwrappin g 25, These wrappingsj and 26 will pullthe'h'ousin'g l9and'rodendfM together. Then there are applied a fifth" series of aboutfive hori'zontal' wrappings 28, to format neck of thef' wrappin'gsbetweenthe housing 19 and the rod end 14. This tends to pull-down a hook29,

which forms a part of an axle hood including the housing 1 9. While 'Imay u'se'the hook 29 forthis purpose, itis to be understood that anyother eyemember may be used instead of a hook wherever I have mentionedherein a hook. Then there are applied a sixth series of about three orfour wrappings 363, each horizontally towards the front around thehook-29 (there being a corresponding oppositelyfsupplie'd rear hook 3]on the housing ZO 'aTnd then down behind and underneath each side of theaxle'housing l9 and again horizontally around the front of the hook 29.to make thesaid three or: four wrappings,..so as to pull th'hook 29upwardlysomewhat to give it a di-.

rection inclined towards thefront for the front axle andtowa s meo t e eax e at an'angle of about 10 to the vertical, or nearly vertical, forordinary and fancy skating, but preferably at a still greater;angler'to; the vertical for speed skating (see Fig". 5') althoughanyother angles can be 7, chosen. -Thereupon I apply a seventh-series ofcrossed diagonaljwindings, each of about ten diagonal wrappings 32, 33,and theremay be alternated .repetitionsof these crossed:

diagonal windings indicated diagrammatically at 32, 33 until, around tl'ecro'ssedhousingv t9 and the rod hi, there are. about six. layers ofthese alternating. crosseddiagjonal. windings..- Then there are appliedan eighth set of figure-.8 windings 34,35, the. figure-3 windings 34,about ten in number, being looped under the rod end: 14 fore and aft andcrossed above the housing l9, and the figure-8 windings 3-5, abouttenin-nurm. her, being looped under theaxle-housing l9 and crossed abovethe axle housing I3. Finally,.there can be added on the. outside aninth. set of alternatin'g diagonalwrappingslike thewrappings 32, 3.3,with more orlessof the wrapping's 32 or- 33 in one direction, tomake'the distance between the right side rollers. equal to thedistance'between the'left, side rollers.

It will be noted from Figs. 1,. 5, 6 and 14, that the book 29 isattached at theifro'nt and rear of the skate to a hook 35, secured to aplate 36 attached to the wooden plate 2 by screws 31 passe ing through;slots'38 so that, if desired, by'the lateral adjustment of the plates 31the four rollers 5 and 6 can be adjusted so as to occupy the samehorizontal plane. The hook 29 can be secured to the hook 35 to suspendthe latter, by further wrappings of a cord or cords of rubber or rubbersubstitute 39, or both, preferably a rubber substitute underneath andrubber outside. Also, as shown in Fig. 6, the hook 35, at the front orback of the skate, or both, will preferably be located to one-side -orthe othen as desired, of the hook 29, before applying the \vrappingsthereto.- Metal contact between the same is avoided by the positionshown in Fig. 6, of the windings applied thereto. A first series ofabout three to five windings 4!! is applied vertically around the twohooks-'29 and 35 to bind them together. Then a second series of aboutfive or six windings M, which actually spread the hooks apart as in Fig.6, is applied-horizontally around the windings 40. Thereafter, a thirdseries of windings 42, like thewindings- 40,1 applied; Finally a fourthseries of abouttwentywindings43 is applied; hon-.- zontally, like-thewindings 4;l The windings 43, o theind n s or bot serve to separatetheltwo-hooks; 2s-and 35 to preventmetal to metal. ont c Asshowm-in Fig. 1,amodifi'ed form of adoue hie-hook 44;,inthe; place of the hook35, canb'e used so to have two laterally directed strad dlingshooksi=45 and'46,: which may be each attachedto the hoo'k 29 bysimilai wrappingstothose applied'to the hooks 29. and 3 5, as for in stance; "alternatinglayers of, each, about five windings .41 and 48 =going around "the hook29- andrthehook45, and around the hook 29 and *the} hook'ldrespectively; Eas well as a" series of about twenty. horizontalwindings wgoing between thehook 29 ahd thehooks '45 and to separate thehooksr-ziIn this -wam thestraddling of the hook 29 by the hooks '45 and46 provides a suspension by the-latter from the hook-29.-

As shown in Fig? l5,"stil-l a other'form of hook 53, whichis arrangedtransversely of the foot, maybe p rovided'in the place of the book 35In, this instancethe hook-29 passesthrough the hook, 5H "and, ifdesired', 'th e latter: may, but not necer. sarily,-have thereon apreliminary winding 5 of a rubber-or rubbersubstituteoord. Also, thisoranother similar cord maybe applied to bind the. hooks 2,9a'ndfifitowards each other by provid-. ing; first, alternatingjlayers ofabout'ten each. of crossedflayers'of windings 52"a'nd 53,, 'as shown, inFig. l5,v each; layer-being. arranged to go. through bothhooks-iilfand'56. so that in use, when skating, the foot, becomes suspended from thehooks 29 bythe'fhooks 5B." 1

Each of the axlesf'zi and. 22,} which are con structed alike, preferablyhas scorings .54 onthe, middleportionsojas to, firmly position them intheirrespeotive housings i9, '20. Besides,; the. ends of. the axle arescrew-threaded to receive t eo conicalfim er and outer ball. races- 5556 to support series of bearing balls 5? and58. so, 15. to cooperatewith roller races 59, and 6.3 on a sleeve 3| fastened in; each rollerE,a'ndfi. Outside, the outer racesa 53, there is, a..D.-shaped washer 62'"cooperating with a flat area 63 on the undere. side of theaxle 2H,: 22Outside. of the ill-washer EZTtl'iere is a nut Mjto secure, each or" therollers 5 and 6 from lateral displacement onits axle. If desired, theremaybea fibreoil-g-uard 65:10- cated between each ihnenballrace 55and thead jacent part of'the'hoiising 1.9,2 3 -Also,.if desired there maybe.applietit'o, the outside ofeach of the rollers 5 and 6 a dust screws61.

As illustrated in Fig. 8, I have shown another form of suspension meansinstead of the block I. In this instance, instead, I have shown twocylindrical hollow metal standards or struts 68 and 58a, having circularplates 69 and secured thereto, which are fastened by screws II to thewooden plate 2. These cylinders 68 and 58a are closed at the bottom bywelded caps 12 and I3 and are provided with lower front and rear flatcircular areas 14 through which the rod I3 passes, and is provided withlong screw-threads and 15 to receive tapered nuts I] and I8, in additionto the tapered nuts i5, I5, I! and I8 previously referred to.

A variation of the construction in Fig. 8 is cap 66 by means of shown inFigs. 9 and 10, in which the construetion is the same as in Fig. 8except that instead of the unitary rod I3 there are a longitudinallyadjustable front rod I9 and a longitudinally ad-.

justable rear rod 80. Also, in this instance there are welded to theinner ends of the rods 19 and 80, hooks BI and 82 respectively, andaround the two hooks, through the eyes thereof, there are a first layerof about ten horizontal windings 83 of said rubber or rubber substitutecord, and a second vertical layer 84 of about ten windings thereof,which prevent metal to metal contact and strongly return the rods 79 and80 to their alignment from any variation thereof during skating, due toany flexibility in the shoe I, made of leather or molded from rubber andfabric or rubber substitute and fabric materials. If desired, there mayalso be provided a similar attachment comprising hooks 19a and 80aattached to the standards 68 and 68a, said hooks having elastic cordwindings 84a like the windings 84. In this form the flexibility movementis aided owing to the plate 2 being substituted by a twopart plate 85and 86, between which there are two rubber or rubber substitute blocksor plates 81 and 88 attached, respectively, to the inner adjacent endsof the two-part plate 85 and 86. Said inner ends of the plates 85 and 86are bound together by a rubber or rubber substitute cord 89,.

of the above character, which passes through holes 99 and 9| in the twoplates 85 and 86, respectively.

In Fig. 11 I have shown another modified form of suspension which issimilar to that just described in connection with Figs. 9 and 10. InFig. 11, however, instead of the two-part plate 85 and 86 I may use aflexible platform 92 of laminated wood or laminated fabric and rubber ora rubber substitute, to which the standards 68 and 68a, for suspensionof the foot, are attached, when wearing an arched shoe 93. In thisinstance the construction is more rigid than that shown in Figs. 9 and10. Accordingly, there may be arranged higher up screw-threaded rings 94and 95, secured to the supports 58- and 68a, respectively, to receivethe screw-threaded ends of hooks 95 and 97, respectively. These hooks 96and 91 may be bound together, yieldingly, by horizontal 98 and vertical99 windings of the rubber or rubber substitute cord, which, as in allthe other instances of windings therewith herein, the windings areapplied preferably under some tension or stretching.

. In Figs. 12 and 13 I have shown still another form of suspension. Thisis the same as in Fig. 1, except that I provide rods I00 and I 0| whichpass through and are fastened to front and rear struts or blocks, I02and I03 respectively by the tapered.

nuts I5 and I! on the outside of the blocks I 02 and I03 and nuts I04and I05 on the inside of said blocks. The blocks I02 and I03 are securedto front and rear wooden plates I06 and I0! by four U-shapedscrew-threaded bolts I08, I109, H0 and III. and nuts Illa. The blocksI02 and I03 have adjoining tapered inner ends I I2 and H3, to providemore turning space to receive the rollers 5 and 6, which have fourspherical recesses H4, II 5, H5 and I I? to receive two rubber balls H8,H9 of any desired construction, but preferably having a core or body ofrubber or an artificial rubber cord, as above referred to, wound undertension. To apply further compression to the balls H8 and II9 the blocksI02 may have therein eight screw hooks I20, I2I, I22, I23, I24, I25, I26and I21. These screws are bound together elastically in pairs I20 andIZI, I22 and I23, I22 and I25, and I26 and I21, by means of any desirednumber of windings I28 of said rubber or an artificial rubber cord undertension.

In Figs. 16 and 17 I have shown a modified form of elastic suspension ofthe axle housing and the foot plate. In this instance there is provideda bracket I29 of metal having two depending arms I30 and I3I providedwith holes in their ends through which a cylindrical rod I32 passes andis held tightly, or loosely for removability therein, as desired. Thismakes an opening I33 through which the upper end of the hook 29 canpass, although the hook can pass below the rod I32, if desired. Fourscrew holes I34 are provided in the plate I29 for attachment of thelatter to the plate 2. The hook 29 is attached to the bracket I29 bysuspension therefrom with an elastic cord of rubber or a rubbersubstitute, such as that above referred to. For this purpose a firstwinding I35 is made around the rod I32. Then a second winding I39, ofabout five turns, is made diagonally over and around the middle part ofthe hook 29 through the opening I33 and around the rod I32 near the armI30. Then a third winding I31, of about five turns, is made similarlyover and around the middle part of the hook 29 and thence through theopening I33 and around under the rod I32 near the arm I3I. Then a fourthticity and flexibility so as to override all unevennesses in the skatingfloor, without impeding the momentum of the skater due to the elasticsuspension of the skater from the axle hoods or housings I9 and 20. Thisis particularly true due to the underslung position of the rod I3 whichis suspended, without metal contacts, beneath the axle housings I9 and29. Nevertheless, the windings of the rubber or rubber substitute cordswhich suspend the rod I3 from the housings I9 and 20 are such as topermit a very great aneular turning movement while providing forreturning the foot and skate always to its original normal position.This suspending action, with freedom from metal contacts, is alsopresent due to the position of the hooks 35 and 29 so that the formerbecomes suspended from the latter but always returns to the normalposition, neverthe less. It will be understood, also, that the cordwindings can be. applied by the individual skater.

to apply. the degree' of tension or resistance to movement or elasticitydesired by him and that, furthermore, he may even supply his own elasticcords; axles and particular rollers carried thereon,so that he canmakethe final assembly there-- of, as desired.

The same is true in the hook suspension in Fig. .7, wherein the hooks 45and 4% become: elastically suspended from the hook 2c in skatin due tothe elastic cord windings as placed thereon. This of itself gives animportant elastic sus pension irrespective of the form of the attachment of the axle housings". is and=2e to the foot, especially-as theshape of the hooks 45 and 46 always returns the hook 29 to the middleposition between them.

In Fig. 8 the operation is substantially 'thesame as in Figs. 1 to 6.

In Figs. 9 and'll), the operation is similar to thatof Fig. 8, but inFigs.-9' and 10, however, there is still more freedom of action inskating due to the relative possible different rotations of the frontroller 5 mountings from the rear roller 6 mountings, not only onvertical axes but also on horizontal axes due to the elastically boundrubber or rubber substitute plates 3? and 88 bound together with therubber or the rubber substitute binding as, but also due to the hooks l9and 85 and their elastic bindings 84, which,

however, always return the skate to normal position.

In Fig. 11 the operation is similar to that in Figs. 9 and 10, exceptthat here there is a supporting laminated plate 92 for the arched shoe93,which permits a torsional movement in said plate 92 one. horizontalaxis and even some relative axial turning movement on said axis betweenthe supports for the front rollers 5 and the rear rollers 6 owing to theelastic bindings as between thehooks 96 and 91.

In Figs. 12 and 13 the operation is similar to the action in Figs. 9 and10. Here, however, the compression present in the balls i 18 and l isgives a greater resistance to displacement of the foot from the normalposition of the struts 102 and E03 and a more positive return to thenormal position of the skate, Also, a more free or ready adjustment ofthe relative positions of the sup ports for the front rollers 5 andthe'supports for the rear rollers ii can be attained.

In Fig. 15 the suspension is similar to that shown in Figs. 5 and 6, buthere the upper hook Ed is suspended from the lower hook'29, by'theelastic windings E2 and 53, as each of the hooks 29 and-58 passesthrough the other.

In Figs. 16 and 17, another efiective form of suspension of the footfrom the lower hook 29 is provided in that the rod :32 from by theelastic windings I36, I31, I38 and While I have described my inventionabove in detail'I wish it to be understood that many changes may be madetherein without departing from the spirit of the same.
